High voltage crossed-field plasma switch.

摘要

A CROSSATRON switch is capable of operating with voltages in excess of 100kV by the use of a deuterium gas fill to increase the Paschen breakdown voltage, axial molybdenum cathode corrugations (62) to provide a higher current capability, and a Paschen shield (48) that is formed from molybdenum. The terminal curvature (52) of the Paschen shield (48) and of the adjacent portion (54) of the anode (32) are selected to establish a voltage stress at the curved Paschen shield surface within the approximate range of 90-150kV/cm in response to a 100kV differential. <IMAGE>
